OBJECTIVE
To study the chemical constituents of Incarvillea younghusbandii.
METHODS
The chemical constituents were isolated by various column chromatographic methods and structurally identified by NMR and MS evidence.
RESULTS
Fifteen compounds were obtained and identified as isobergapten (1), sphondin (2), imperatorin (3), xanthotoxin (4), phellopterin (5), heraclenol (6), rivulobirin A (7), methyl oleanolate (8), methyl caffeate (9), grevillic acid (10), boschniakinic acid (11), tert-O-beta-D-glucopyranosyl-(R)-heraclenol (12), 5-methoxy-8-O-beta-D-glucopyranosyloxypsoralen (13), 1'-O-beta-D-glucopyranosyl-3-hydroxynodakenetin (14) and phenylethyl-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside (15).
CONCLUSIONS
All of these compounds were isolated from this plant for the first time and most of them are furocoumarins.
